What types of munitions are considered most hazardous during firefighting incidents?

Munitions that contain high-energy explosives, such as artillery shells and bombs, are considered the most hazardous during firefighting incidents due to their potential to detonate under certain conditions, such as heat and shock. These types of munitions are designed to release a significant amount of energy in a very short period of time, which can result in catastrophic explosions.

Their construction allows for both a high level of lethality and the ability to cause large-scale damage, not only to the immediate area but also to personnel and firefighting resources. In a fire situation, if these munitions are exposed to flames, the risk of an explosion increases, which can pose serious challenges to firefighting efforts and create additional hazards for responders.

In contrast, munitions with low-energy mechanisms, non-explosive munitions, and small arms ammunition generally present a reduced level of risk when compared to high-energy explosives. Low-energy munitions may not detonate easily, and non-explosive items do not have the same level of potential danger associated with fire. Small arms ammunition, while it can pose some risk, typically does not create the same level of explosive hazard as larger ordnance like artillery shells and bombs. Therefore, option B clearly identifies
